现在完成时的被动语态的构成形式：

肯定式：have/has+ been+过去分词（句1－句5）；

否定式：have/has+ not+ been+过去分词（句6）；

疑问式：Have/Has+主语+ been+过去分词（句7－句8）。

现在完成时的被动语态通常表示下面两种情况：

1、表示过去开始的被动动作一直持续到现在，句中经常有in the past … years, so far, “for +一段时间”或“since + 具体时间”等状语；

2、表示被动动作在过去发生或完成，但是对现在仍然有影响，句中经常有already, yet 等状语。

注意：在时间、条件状语从句中，通常要用现在完成时的被动语态代替将来完成时的被动语态。如：

I will go to play football as soon as the homework has been finished.

If a plan has been made, we should put it into practice. 【知识链接】
